This course will help prep you to earn the CompTIA Healthcare IT Technician certification showing that you have the knowledge and skills needed to succeed in installing, managing, and troubleshooting IT systems in medical and clinical settings.

Well I created a qucik ActiveX DLL to see if I could maybe re-create the problem that you where having - I even called it the same as yours - but I could not get mine to produce the error that you received.

To that end I found a post on EE that might (might) help - (an answer was accepted)....
